sroo'r. AND THE LIKE.

To all whom it may concern:

Be it knownthat I, OSCAR H. HEINIG, a citizen of the United States, residing at Chicage, in the county 'of- Cook and State of Illinois, have invented certainnew and useful'lmprovements in Spools and the like of which the following is a s'peciflcation.-'

The spool to which the present invention relates is particularly intended for winding electric wire and the like; although manifestly spools embodying the fe'aturesof the present invention may be used for many other purposes. 1

One feature of the present invention has reference to the'construction of spools having their body portions made of wood or other grained material; and in this connection one of the obj ectsof the invention is to provide a construction of spool, such that when madefrom wood or other grained ma terial it may be made with a minimum amount of wastage. This feature of the invention will be understood when it is considered that in the case of a spool cut or turned from a solid blockof'wood it is necessary to use a block whose original dimensions in the used in building up the spool;

three principal directions are at least equal to the ultimate dimensions of thecompleted spool. In this connection, one of the objects of the inventionis'cto provide a built up construction of such design and arrangement'that the various parts or sections thereof mayeach be cut with a minimum percentage of wastage of raw material Another .feature of the invention relates to the provision, in built-up spools, ofiametallic sheeting -or coveringfor certain portions thereof. J Other objects and uses of the invention will appear from a detailed description of the same,-which consists in the features of construction and combinations of parts hereinafter described and claimed.

In thefdrawingsz. 'Figure 1' shows av longitudinal ;sect1on through a spool embodying the features of the present invention, the inside faces of the end flanges being surfaced orsheeted with metal. Fig. 1 may be considered as a section taken on line"1' 1 of' Fig. 2 lookingin the direction of the arrows; v

Fig. 2 shows an end view of the spool of Fig.'"1;

facing sheets before the edge flange thereof has been turned down;

Fig. 5 is an inside face view. corresponding to Fig. 4; a

Fig. 6 is a side elevation of one of the hub spindles showing the longitudinally extendmg grain thereof; I

Fig. 7 is a face view of one of the flange disks showing the cross grain thereof; and Fig. 8 is a fragmentary view correspondmg to Fig. 1 withthe exception that it shows a modified type of construction.

Referring first to Fig. 1, there will be observed the, central spindle section 10. This is ordinarily-of cylindrical form, being provided with a longitudinal perforation 11. The end flanges are designated in their en= tirety by the numerals 12' and 13 respectively. I will first describe the construction of one of these end flanges of the type shown in Figs;v 1 and 2, and will afterward describe tlie'lmodifiecl construction. shown in Fig. .8. Each of the end flanges includes a flat relatively thin disk 14: of wood or the like; and when grained material; such as wood, is used, it is, preferred that the disks 14 be cut out of a narrow board of a thickness substantially equal to the thickness of the disks, so as to out said disks with a minimum of wastage of material.

The central portion of each disk 14 is pro vided with a-circular opening 15 into which seats a hub 16. Each, of the hubs 16 has' central. neck portion 17 generally. of

tapered form. which is adapted to seat snugly into the end of the longitudinally extending passage 11 of the spindle 10. Each hub is also provided in some cases with an outwardly extending flange 18 of diameter to seat snugly within the opening 15 of the corresponding disk 1 1; but whether the flange 18 be provided or not,. the opening 15 should be of sucha size as. to snugly rethe-hubs and flanges or disks from twopieces it is possible to greatly economize in the amount of rawmaterial necessary, which is a very important item owing the rapidly diminishing supply of suitable lumber.

The necks 17, if desired, maybe pinned to the spindle by the transversely -extending pins 19, but this is optional with the designer. Ordinarily a pair, of openings .20

flanges for the accommodation of the .end portions of the wire or material intended to be-woundcnthe spool; and if desireda hole 20 may be provided in the other end flange It is to be observed, from an examination particularlyofdi ig. 1, that theend portions ofthe spindle1O project slightlyinto: the flange portions 12 and 13,. so that there isa certain amount. ofoverhang established. A

' convenient wayof bringing about this re sultis to formithe openings 15 of substantiallyrthe. same. diameter as theaspindle 11 0, and in-su'ch case make'the flangeslS slightly thinner thanithe disks 14, so that when the outer surfaces of-thehubs and their disks are brought flush together, asshown inrFig. 1, a shoulder-will be. established for the accommodation of thecorresponding end por- 7 tion of the spindle 1' 10.

I In many cases it "will befidesirable' topro- V vide a metallic. facing 20 on the inner: face of the. 'disks. 14;-and when the same is used it may be made "of-the form shown in detail in Figs. Land 5. rAstherein illustrated, its centralportion '23 is slightly depressed to correspond with ithe shoulder aforementioned, and its innerperipheral portion is inturned to-eprovide-a series of lugs or the like :24. These lugs maybe driven into the grain on the end of' the spindle 10 but ordinarily a groove 25 will first be formed in the end of the spindle so as to guidefthelugs and insure that they will a'llcome to a proper seat within the grain; v The flange portion 24 of the sheeting 22 may be inturned or; beaded over' against the outer face of thecorrespon'ding disk "14, as

shown in Figs. 1 and'2, and when this is done itwill generally-be desirable to provide a peripheralgroove orshoulder in the disk,=so that the completed spool will present-a'flush outside or-endsurface, as shown in'Fig. 1.
